Papyrus: Exception after applying CSS to model


I applied a CSS to a model, and after that I was no longer able to work with it, it does not even get rendered. Now every time I try to open it I get the following exception:

Java.lang.ClassCastException: org.eclipse.e4.ui.css.core.impl.dom.Measure cannot be cast to java.lang.Integer

The Properties view now only shows the message "Properties are not available", thus I cannot remove the CSS. Is there any hope of saving this model?

Thank you.


Solution

  • The excpetion was being caused by an error in the CSS file. I had a few colours defined:

    @variables 
    {
        myRed: #ff7777;
        myCyan: #55ddff;
    }
    

    And later on had a style with:

    [appliedStereotypes~="Stereo"]
    {
        gradient: myRed vertical;
        background-color: myCyand;
        bold:true;
        shadow:true;
        elementIcon:true;
        qualifiedNameDepth:full;
    }
    

    After replacing myCyand for myCyan the model became functional again.

    Unfortunately no elements in the model are getting styled, but that is another question.
